The edges of her vision turned dark gray, then black.

A strange, terrifying warmth flooded the back of her neck. He’s going to kill me. That was her last coherent thought before her limbs went slack. A second later, the pressure vanished. Air rushed back into Sarah’s lungs with a harsh, ragged wheeze.

She curled onto her side, coughing violently, her chest heaving. Tears pricked her eyes, not from sadness, but from the raw, physiological shock of oxygen deprivation.

Her throat felt bruised, a deep, throbbing ache radiating down to her collarbones. Derek stood up, tying his belt with practiced nonchalance. He looked down at her.

“You got to tap earlier, Sarah. Don’t let your ego get in the way. In a real fight, nobody stops. ” He said it loudly, ensuring the two adjacent pairs of grapplers heard him. Sarah pushed herself up onto her elbows, still coughing. She felt humiliated, stripped bare.

She had tapped. She had tapped immediately. He knew it. She knew it. But in the tribal hierarchy of the gym, no one had seen a thing.

The adjacent pairs kept their heads down, pretending they hadn’t heard her frantic slapping on the mat.

Derek turned away, looking around the room for his next victim. “Who’s next? ” he called out, cracking his knuckles. “I am. ” The voice came from the edge of the mats. It wasn’t loud.

It wasn’t aggressive. But it cut through the dull roar of the gym like a scalpel.

Cole uncrossed his arms and stepped away from the cinder block wall near the entrance

. He wasn’t a member of Apex Grappling. He was just Sarah’s older brother, a man who had driven down from San Diego to help her move apartments that weekend.

He’d arrived 10 minutes early to pick her up, standing quietly in the shadows by the cubbies.

He wore a plain black rash guard and a pair of gray athletic shorts. At first glance, he didn’t look like much. He was lean, hovering around 180 lb, no cauliflower ear, no flashy gym apparel.

But there was a stillness to him.

The kind of absolute terrifying calm that only belongs to men who have done violence for a living.
